Abstract

It is one part for calibration of oscilloscope probes. It is coupled onto an oscilloscope for stable contact with various probes of the oscilloscope. It includes one face panel that has at least one empty fixture of the first probe and at least one fixture of the second probe thereon. The top face of such first probe fixture is divided into several spring leaves that extend from the edges to the center for the clamping of metal rods of the second probe. In addition, the second probe fixture includes one clamping board and two projecting brackets installed on the face panel. The two brackets have two holes therein and in the middle of both sides of the clamping board is one projecting pivot to accommodate the previous holes. At least one spring shall be connected between one end of the clamping board and the face panel so that the compression and release of the spring can drive the clamping board against or release it from the metal wires of the first probe. This utility model can properly fix various probes commonly seen in the market and thus ensure the availability of stable and accurate test waveforms.

Description

The verification accessory of oscilloprobe

[technical field]

[background technology]

For the measuring error that makes DQA when test minimizes, each channel that needs will use oscillograph before each test is done verification, its method is that the oscilloprobe more than two or two is connected on the verification accessory simultaneously, be benchmark with a channel then, regulate the deviator of the time shaft of other channel, make mistiming of signal of itself and benchmark passage as far as possible little, this step is the indispensable part of test, the use of finding the verification accessory of all oscilloprobes now all is not very convenient, with Fig. 1 existing probe to the market shown in Figure 3 is that example describes: the probe of the probe of first among Fig. 11 is made up of two soft alloy leads 11, if use the probe of first more than two or two 1 simultaneously, because plain conductor 11 is softer and thinner, be difficult to stable the contact with the verification accessory, need be during use with hand with its surface that is pressed on the verification accessory to transmit signal, one loose one's grip slightly, the phenomenon of shaking even disappearing will appear in signal; The probe of the probe of second among Fig. 22 is two hardmetal bars 21, though two probes of this second probe 2 are harder, can put eaily on the surface of verification accessory, can be owing to fix relatively difficulty of the probe of second more than two or two 2 with a hand, probe also is easy to slip; The signal end 31 of the probe of the probe of the 3rd among Fig. 33 is Metallic rod, and the ground end is a jack, use for lead 32 insertions of band acupuncture needle, so it has gathered the shortcoming of above-mentioned first, second probe 1,2.

In view of this, be necessary to provide a kind of verification accessory of stablizing the above-mentioned various probes of contact in fact.

[summary of the invention]

The purpose of this utility model promptly provides a kind of verification accessory of stablizing the various probes of contact, is easy to the problem of slippage verification accessory in order to the Metallic rod of the plain conductor that solves above-mentioned probe and loose contact of verification accessory and probe.

For reaching above-mentioned purpose, the utility model provides a kind of verification accessory of oscilloprobe, be coupled on the oscillograph, can stablize the various oscilloprobes of contact, it comprises a panel, and this panel is provided with the first probe fixture and at least one second probe fixture of at least one hollow, wherein, the end face of this first probe fixture is split into some shell fragments that extend to the center from the edge, Metallic rod in order to clamping second probe, again, this second probe fixture comprises that clamping plate and two are convexly set in the support on this panel, and be respectively equipped with two pivot holes on this two support, and these clamping plate two middle side parts outwards are convexly equipped with a pivot that can insert in the above-mentioned pivot hole respectively, and be connected at least one spring between this clamping plate one end and this panel, drive these clamping plate and unclamp and the plain conductor that clamps first probe with discharging with the compression that utilizes this spring.

In sum, on a verification accessory of the present utility model, be provided with two probe fixtures at least, and this two probes fixture adopts gripping and inserted mode fixedly to have an oscilloprobe of plain conductor and Metallic rod respectively, then when the probe verification, can keep probe to contact with the good of this verification accessory, thereby obtain stable and accurate test waveform, make this task of probe verification can more convenient and quicker and more effectively finish.
